A WATER-SAVING DEVICE

Abstract: The water-saving device makes is possible to portion a certain amount of water while flushing. The water-saving device comprises a push-button (5), which is fixed in a cup-shaped part (1). Inside the push-button (5) adjustable push-elements (4) are mounted, through holes (10) in the cup-shaped part (1). Between the cup-shaped part (1) and the push-button (5) a spring (7) is mounted. The cup-shaped part (1) has a connection element (2) for the lifting rod (3). The ends of the push-elements (4) are supported by a fixed support (9) on the toilet. When the flushing is actuated, the push-button (5) and the cup-shaped part (1) are pressed together and the movement of the lifting rod (3) is limited. The movement can be adjusted by threads (6) on the push-elements (4). The amount of water depends on the actuation time and how the push-elements (4) are adjusted.

Description: A_ w a t ^ r_ - s a_ v .in £ _ d_ j. £ The present invention relates to a water-saving device for water closets with a lifting handle actuator for discharge of an optional amount of water, comprising actuator means fixed to the lifting rod and mobile in relationship to each other. This kind of device is known from FR, Al , 2 609 297, where the flushing is controlled by a concentric tube mounted around a rod. The rod and tube are connected with a valve and mobile in relationship to each other. The tube is conncected to an actuation flange. When the tube is moved towards a knob connected to the rod the valve opening is limited (d) , and a partial flush is discharged. When pushed, the knob causes the rod to open the valve more (D) , thereby discharging a full flush. Moreover, from SE, 211 510 a flushing device for flush- ing different amounts of water is known, where the lift is limited by a leverarm engaging the lifting rod bene¬ ath the push-button, and a full flush is obtained by pushing the push-button. The object of this invention, is' to show a cheaper and more simple lifting-device, for optional flushing, which can be mounted on an ordinary lifting rod, found in water closets with a lifting handle actuator. This is achieved through a lifting device including a cup-shaped part screwed onto the lifting rod, the cup- shaped part having an actuation-flange, an internally mounted push-button affected by a spring to repel the cup-shaped part's bottom from the push-button, and push-elements mounted through holes and adjustably fixed to the push-button. The obtained unit is screwed onto the lifting rod of an ordinary water closet after the removal of the normal actuator-button. In its passive position the cup-shaped part's bottom is supported by a fixed support on the toilet . When flushing, the push-button is pushed (e.g. with the thumb) and the cup-shaped part's flange is lifted and pressed up against the push button. The push- elements stay in their position supported against the toilet. The lifting rod is raised to a height limited by the push-elements. The button is held in this posi¬ tion for as long as a partial flush is wanted. During a full flush the cup-shaped part's flange is lifted without pushing the push-button. Henceforth, the push-elements will be in the form of screws, mount¬ ed through holes in the cup-shaped part and screwed into the bottom of the push-button. The amount of water to be used when using the partial flush is adjustable by changing the length screwed into the push-button. Preferably, the screws are sunkscrews, which are sunk into an lie against the bottom of the cup-shaped part when the push-button is in passive position. Hereby, the push-button is situated inside the cup-shaped part fixed by the pressure of the spring and the sunkscrews sunk into the cup-shaped part. The screws make it possible to adjust the amount of water to be discharged during a partial flush, and the screwheads are supported by a fixed support on the toilet . Henceforth, the spring is supported by a recess situat¬ ed in the central part of the cup-shaped part, and an axial recess in the push-button (5). This means that the actuator is very sturdy. Preferred embodiments of the invention will be describ¬ ed below in conjuction with the accompanying drawings. Fig. 1 shows a cross-section of the invention in a passive positon Fig. 2 shows a cross-section of the invention during a partial flush operation Fig. 3 shows the invention during a full flush opera¬ tion. Fig. 1 shows a cross-section of a water-saving device including a cup-shaped part (1) with connection ele¬ ments (2), e.g. threads, for the lifting rod (3). The cup-shaped part (1) has two holes (10) for the push-elements (4), e.g. screws, which are screwed on to the push-button. Between the cup-shaped part (1) and the push-button (5) a spring (7) is mounted to repel the cup-shaped part (1) and the push-button (5) from each other. In fig. 2 the push-button (5) and the cup-shaped part (I) are pressed together, the screws (4) are adjustable to limit the movement of the lifting rod (3) . The space (II) between the cup-shaped part (1) and the push- button (5) can be adjusted by threads (6) on the push- elements (4) . The screwheads (8) are supported by a fixed support (9) on the toilet when the push-button (5) and the cup- shaped part (1) are pressed together, thereby lifting the cup-shaped part (1) and the lifting rod (3) a limi¬ ted distance. In fig. 3, the cup-shaped part is pulled so that the lifting rod (3) activates a full flush.

Claims: Claims 1.
